bitsensor 4 axis cnc mach3 usb controller

Provide 4 output port (5V level), can be connected with the relay module opto-coupler, water control, spray and so on.Optical isolation between the USB side and the external input.All input signals are isolated by optical coupler.4 digital input input protected by opto-coupler.Step pulse frequency up to 100 khz which make it suitable for smooth stepper or servo motion.In fact, you can use tablet with USB port to control your 4 axis machine with Mach3 software. No need for old computers with parallel port. This means that you can run your 4 axis CNC machine with Mach3 software using windows operating system and USB port. It allows you to control up to 4 CNC drivers with 4 stepper or servo motors. NOTE: If spindle is not driven directly by a motor but via transmission with some ratio other than 1:1 and if revolution sensor is located on the motor and not on spindle itself, then to enable correct spindle speed calculation, correct transmission ratio should be configured using Pulley setup dialog.This is 4-Axis USB CNC Motion Controller for Mach3. If this option is enabled, averaging of revolution speed is performed to obtain more stable display of numerical value.įigure 4 option for Spindle speed averaging If needed, option Spindle Speed Averaging (figure 4) can be enabled. If everything is right, now on Mach3 main screen in Spindle Speed group, field RPM should show real spindle revolution speed in RPM (figure 3).įigure 3 Monitoring spindle revolution speed USB-MC motion controller supports more than one pulse per spindle revolution, so the correct value should be entered in USB-MC configuration: menu PlugIn Control->USB-MC config./ General Setup/Index pulses per revolution. If spindle is rotated and there is no change of state on Index input, something is not correct with software setup and/or wiring and the problem should be found and corrected. Status window of USB-MC controller displays real current state of digital inputs (high/low), while Mach3 Diagnostics screen shows whether signals are active/inactive in respect with their individual active low/high settings.

To test whether Index input is working it is possible to use Mach3 Diagnostics (Alt-7) screen (figure 2), or status window for USB-MC motion controller.įigure 2 Status of input signals is shown in the bottom right corner of Diagnostics screen In this example Index input is placed on pin 1.įigure 1 Index input, pin and port configuration With USB-MC motion controller, port number is always 1, and pin number is adjustable as desired in range 1-14 (depending on digital input line where Index signal is connected). To configure pin and port for Index input in Mach3 software, dialog Ports&Pins/Input Signals (figure 1) is used. This item: RATTMMOTOR 4 Axis CNC USB Mach3 Controller Breakout Board CNC Motion Controller Card Stepper Motor Driver with Cable for CNC Router Engraving Machine, Servo Motor, Stepper Motor 31.00 31. Signal from this sensor must be connected to Index input. For spindle revolution speed monitoring, besides USB-MC motion controller, some revolution sensor is needed to provide at least one pulse per spindle revolution.
